VENTILATING WATER-CLOSET.

Specification of Letters Patent.

Patented July 2, 1907.

Application led January 11,1905. Serial No. 240,579.

To all 'whom 'it may concern:

Be it known that I, CECIL HOLMES THOMPSON, a subject of the King ofGreat Britain, residing in the city of Toronto, in the county of York,in the Province of Ontario, Canada, have invented a new and usefulImprovement in a Ventilating Water-Closet, of which the following is aspecification.

My invention relates to the arrangement of the combination of a seriesof valves, whereby in the use ofthe water closet, and the weight appliedto the seat, by the user ofthe closet, will cause the water to passthrough the valve casing, through the valves, and escape into a spraynozzle arranged in a vent pipe communicating with the bowl of thecloset. By the escape or the egress of the water through the nozzle asuction is created, which draws all the odor from the closet, and forcesthe same with the spray up through the vent pipe. The water after it haslost its force from the nozzle flows back into the bowl through the ventpipe.

The device is so arranged and constructed that the spray and suctionwill be continued while the weight is on the seat, and after the weightis removed from the seat the water causes the different valves to close,and the different parts to return to their respective or startingpositions, and the Ywater to shut ofi. Further the operating valves arearranged in combination with a small regulating valve, whereby thevalves may be set to close ofi at any desiredI or pressure, so that anydesired or length of time maybe given for Ventilating the closet. I mayalso arrange the device to operate in combination with the Hushingoperation of the closet.

I attain these objects by the device as illustrated inthe accompanyingdrawings, in which- Figure 1 is a perspective view of a water closetbowl, with the parts of my invention in combination; Fig. 2 is asectional elevation of the valves and connecting parts; Fig. 3 is across sectional view through the valves; and Fig. 4 is a detailsectional view of the nozzle and vent pipe.

Like letters refer to like parts throughout the drawings andspecifications.

In the drawings I show a water closet bowl a, of the ordinary type,provided with a hinged seat b, and a lid or cover c. Extending rearwardfrom the top plane of the bowl is an extension d, and on this extensionis bolted the valve casing e. The valve casing is cast to form a pair ofparallel cylinders f and g, in which work up and down a valve h and apiston i respectively. Screwed into the top oi the cylinders j" and g,are suitable caps j and 7c, provided with any ordinary packings to fitaround the spindles Z and m, of the respective valve and piston h andt', which extend up through and above the top of the valve casing, andare formed integral with the pistons. Arranged in the cylinder f is avalve seat n, on which engages the valve h, and passing from thecylinder f into the cylinder g is a port o, provided with a counter boreo, in which engages a ball p. The ball is retained in the bore o, by asmall spiral spring q supported and retained by a pin r, projecting froma plug s, screwed into the side of the cylinder f, opposite the port o.Passing through the bottom oi the cylinderf is an inlet t, surrounded bya screw threaded collar u by which may be coupled the feed pipe '0,through which the water is supplied to the valves.

In the upper part of the cylinder above the valve seat n, is an outletport' w, which communicates with thespray pipe x, which terminates in anozzle x/, and enters into the vent pipe y. The vent pipe y is coupledwith an opening l in the side of the bowl, and may be carried to theroof of the house. The nozzle x/ may be of any desired shape 'orconstruction adaptable for the purpose specified. lThe design of the oneshown in the drawings is of the simplest form, and is shown merely fordescription.

Extending into the web of the valve casing between the cylinders f andg, is a small regulating screw valve 2. The screw valve 2 consists of atapered head 3, provided with a shank 4 and terminating in a thumb nut5, which projects through and beyond the packing nut 5C The head ,3maybe turned to regulate the amount of passage from the cylinder f tothe cylinder g, through which the water passes into the cylinder g, andcauses the piston i to rise.

Communicatingr with the valve 2 and engaging with the tapered head 3 isa port 6 from the cylinder f, and communicating with the valve 2, andthe cylinder g is a port 7, by which the water may be regulated t0 flowfrom one cylinder to the other. The water enters in through the inlettin the bottom of the cylinder f, and passes through the port 6, throughthe valve 2, and through the port 7 into the cylinder g, and forces thepiston upwards, until its limit is checked by the valve h, engaging withthe valve seat n in the cylinder f. The spindles l and m of therespective valve and piston h and i, are coupled together by a yoke 8,fastened to their upper ends, so that both valve and piston travel inuni son and simultaneously. Connected into the upper end of the cylinderg is a small vent pipe 9, by which the air or any water that may getabove the piston may be drained of. The vent pipe 9 may be carried downto discharge into the iiushing pipe l0, or may be carried directly intothe bowl.

Formed integral with the valve casing a, and projecting upwards fromeach side and terminating in an elongated head 11 is a lug 12, to whichis pivoted a hinge operating plate 13. Through the head ll ofthe lug 12are a series of bolt holes 14, by which the plate 13 may be pivoted tothe lugs l2 by bolts 15, the series of bolt holes 14 are lor the purposeoi adjusting the parts for the different conditions of seats. Fastenedto the back edge o the seat b is a fastening plate 16, having twoupright extending lugs 17 provided with circular heads4 18,

adapted to engage with the front edge of the operating plate 13.Fastened to the top back edge of the lid or cover c, is a hinge plate19, provided with two rearwardly extending lugs 20 terminating incircular heads 21. The lugs 20 and 17 are so arranged that they fit oneither side of the front edge of the operating plate 13, and passingthrough the heads 18 and 2l respectively, and through a circular opening22 in the plate 13 is a bolt 23, by which the seat and the cover will behinged to the operating plate 13, and also hinged to the valve casing e.The plate 13 is so arranged that the under side rests on the top of thespindle m, of the piston i, and by reference to Fig. 2 of the drawingsit will be noticed that when the piston is in its raised position, itkeeps the back edges oi the seat and cover slightly raised from the topplane of the bowl a.

When in operation a weight is placed on the seat b, the seat is causedto lower to the horizontal, which draws the operating plate 13 downward,and presses on the top of the spindle m of the piston t'. With thedownward travel of the piston il the water in the cylinder g is orcedout through the port o, and by the force of the Water the ball p isforced away from the port, at the same time being kept in its re'laiveposition with the counter bore o by the spring q on the pin r within thecylinder f. At the same time the piston t is traveling downward in thecylinder g the valve h, in the cylinder f travels with it, and movesaway form the valve seat fn, which allows the water to pass through theport m into the upper part of the cylinder, and out through the port w,into the pipe x, where it sprays through the nozzle x, into the ventpipe y. The nozzle will be pointed to discharge away from the closetbowl, and any suitable design of a nozzle may be adapted, suitable forthe purpose. A small amount of the water will find its way of escapethrough the ports 7 and 6 of thevalve 2, but the port o will provide forthe greater, and quicker escape of the water from the cylinder g intothe cylinder f. This operation of the valves takes place as the pistonil is being forced downward by the seat, and the plate 13 bearing on thespindle m. As the valve h and piston t' are coupled together to operatein unison by the yoke 8, fastened to their respective spindles m and Z,their travels will be simultaneous, and as soon as the weight is removedfrom the seat the valve and piston start to travel upwards, by thepressure of the water on the underside of the piston t', that has passedthrough the ports 6 and 7 into the cylinder g. All the time the water isfilling the cylinder g, the water continues to spray through the nozzlerv, and continue spraying until the water is cut off by the valve hengaging with the valve seat n in the eylinderf. The valve h engagingwith the valve seat n, closes off the supply of water from the spraypipe 9;.

By regulating the port oiingress from the cylinder f into the cylinder gthrough the valve 2 it will be understood the spray may be continued anydesired length of time, and the adjustment may be effected by screwingthe plug 3 in or out, and as the weight has been removed from the pistont', the water is free to force its way intothe cylinder g, and the ballp is forced by the water to fit against the port o, thereby closing anyinlet through the port o, which will only allow the water to find inletthrough the ports 6y and 7 in the valve 2, which will be adjusted to beas slow as possible providing for as long a spraying operation as isneces- Slly,

The iront part of the valve casing is provided with a lug 25, having aseries of bolt holes by which it may be fastened to the bowl, or theprojection oi the bowl-d.
